64-326 12.5 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=1.5 mm 850nm

The 64-326 is a high-performance Shortpass Filter, boasting a 12.5 mm diameter and a thickness of 1.5 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is specifically designed for applications that require the efficient transmission of light below a certain wavelength, in this case, 850nm, while blocking or reducing light above this wavelength.

The Shortpass Filter features a unique coating on both the front and back surfaces, identified as 'edm 64-326'. This coating enhances the filter's performance, providing a high level of precision and reliability. The filter's geometry, including its diameter and thickness, is optimized for compatibility with a wide range of optical systems, ensuring ease of integration and efficient operation.

The filter's physical data, such as the cut-on and cut-off wavelengths, are finely tuned to provide the desired optical characteristics. The cut-on wavelength is 0nm, indicating that the filter begins to block or reduce light immediately upon the onset of the spectrum. The cut-off wavelength is 850nm, beyond which the filter significantly attenuates or blocks light.
